KJF Series - Tunnel Jet Fan Product Overview

• The KTF Series tunnel axial fans are made of high-strength materials and are suitable for tunnel ventilation applications, such as traffic tunnels, underground buildings, utility tunnels, wind tunnel tunnels, etc.

• The fans adopt a surge-free design or anti-surge device to ensure stall-free operation, thereby protecting the fan and upstream/downstream equipment in the airflow from damage.

• Reversible airflow direction is available (97–100% reversibility).

• The fan's air performance has been tested and certified by AMCA, in compliance with AMCA 210 standards.

• Suitable for high temperatures up to 400°C/2 hours, with EN 12101-3 certification provided by globally renowned third-party testing and certification organization TÜV SÜD.

• All impellers are statically and dynamically balanced and comply with ISO 1940 and AMCA 204 - G2.5 standards.

KJF Series - Tunnel Jet Fan Product Construction

• Casing

  The casing is made of high-quality carbon steel plate with a thickness of 6 mm or more, suitable for tunnel/underground environments.

• Blades

  Specially designed homogeneous aluminum alloy airfoil blades with high yield strength, suitable for high-pressure applications and thermal shock during fire.

• Structural Support

  The fan support is made of high-strength steel plate and can withstand static and dynamic loads during fan operation.

• Surface Treatment

  All carbon steel components can be hot-dip galvanized for corrosion resistance and high-temperature resistance.
